Script compliance and agent feedback

ABSTRACT

Systems and methods are provided for using automatic speech recognition to analyze a voice interaction and verify compliance of an agent reading a script to a client during the voice interaction. In one aspect of the invention, a method may include a voice interaction, wherein the agent follows the script via a plurality of panels. The voice interaction is evaluated via the plurality of panels employing panel-by-panel playback with an automatic speech recognition component adapted to analyze the voice interaction. As such, it may be determined, via generating a score using confidence level thresholds of an automatic speech recognition component such that confidence level thresholds are assigned to each of the plurality of panels and evaluating the score against at least one of a static standard and a varying standard, whether the agent has adequately followed the script.

SUMMARY OF THE INVENTION

Apparatus and methods are provided for using automatic speechrecognition technology to analyze a voice interaction and verifycompliance of an agent reading a script to a client during the voiceinteraction. The apparatus and methods are particularly suited for usein any situation where a voice interaction takes place in which at leastone participant is obliged to follow a prepared script, and areparticularly suited for use in the operation of a call center, such as,for example, to evaluate or verify that call center agents are properlyreciting scripts during telephone or web-based calls to or from callcenter customers.

In one aspect, a communications system includes a voice communicationsnetwork providing voice connectivity between a system user and a callcenter. The call center preferably includes a call control device forreceiving and routing calls, one or more agent workstations at which anagent is able to process an incoming or outgoing call, and a scriptcompliance module for analyzing a voice interaction between the systemuser and the agent. The system user is able to access the communicationssystem with any type of voice communications device, including, forexample, a telephone, a voice-capable computer, or a wirelesscommunications device. The voice communications network is provided withany form of voice communications capability needed to support the user'svoice communications device, such as a digital communications network,standard telephone network, internet-based, or wireless network. Thecall control device provides the functions of receiving the voicecommunication from the communications network and routing the call tothe agent workstation. The agent workstation will typically include atelephone and a computer, with the computer being optionally networkedto a database for data access by the agent.

The script compliance module is provided with an automatic speechrecognition (ASR) component, such as that provided by aspeaker-independent, continuous speech, multilingual, multi-dialect ASRcomponent such as those known in the art. The ASR component is adaptedto receive a digital signal representing a voice interaction between thesystem user and the agent, and to provide an output of an analysis ofthe digital signal for use in a quality assurance (QA) process.

In another aspect, a method is provided for analyzing a voiceinteraction and verifying compliance of an agent reading a script to aclient during the voice interaction, for example, as part of atelemarketing campaign. The voice interaction preferably takes placebetween a system user and an agent over the communications network, butmay alternatively be a face-to-face voice interaction or any voiceinteraction capable of being captured and analyzed by an ASR component.The agent may be physically located within the call center, or may be ata distant location, but the voice interaction is preferably routedthrough the call control device at the call center. In the preferredembodiment, the agent is responsible for referring to and following aprepared script for at least a portion of the voice interaction. Thevoice interaction is captured, converted to digital form, and exposed tothe ASR component, in real-time or in a recorded form, and the ASRcomponent analyzes at least a portion of the voice interaction. Theanalyzed portion is compared against a standard, preferably the expectedcontent from the prepared script or script portion associated with thegiven portion of the voice interaction, and a determination is madeconcerning the extent to which the agent complied with the script duringthe voice interaction. For example, one or more portions of the voiceinteraction may be assigned a score to indicate a level of scriptcompliance by the agent, as determined by the ASR component, and takinginto account any limitations (e.g., confidence-level thresholds) in theASR component's ability to evaluate the voice interaction.

In yet another aspect, one or more actions are taken based upon theabove script compliance determination. In a preferred embodiment, theseactions are taken as part of a quality assurance or employee incentiveprogram. The actions include, for example, sending the voice interactionto a quality assurance monitor for review, assigning the agent forrandom voice interaction review, sending an e-mail or other flag to anoversight authority for review, sending a voice or text message to theagent, updating a file associated with the agent, updating an incentiveprogram to reflect the compliance determination, or other such actions.

In yet another aspect, a scripting package and quality assurance processare constructed to provide panel-level review of a voice interactionduring the quality assurance process. The scripting package preferablyincludes a plurality of call scripts used by the agent during the voiceinteraction, a log record layout including provision for each valuelogged during the voice interaction, and a plurality of ASR referencetexts corresponding with the plurality of call scripts. The voiceinteraction is recorded and logged, including a timestamp and timedisplacement for each script panel occurring during the voiceinteraction. The quality assurance process includes a provision forretrieving and reviewing the recorded voice interaction by panel level.Accordingly, if a script compliance scoring system is used, the scoremay be retrieved and reviewed for each panel forming a part of the voiceinteraction without having to review the entire voice interaction.

Several advantages are obtained through use of the apparatus and methodsso described. For example, the described apparatus and method provide ascript compliance function having a wide range and scope of applicationsat a relatively minor expense when compared to non-automated managementsystems. By employing an ASR component to analyze and evaluate the voiceinteractions, a call center provider can decrease or avoid the need tohave individual managers or other call reviewers perform thosefunctions. This becomes particularly advantageous to call centers havingseveral agents, perhaps dozens or hundreds, or where the agents are notphysically located on the call center premises.

A further advantage obtained by the present apparatus and methods is theability to provide useful information concerning agent script complianceto a quality assurance (QA) authority in a time-effective manner. Forexample, when the apparatus and methods are used in real-time, a reportmay be submitted automatically to a QA authority almost immediatelyafter a given voice interaction is completed. Where the voiceinteraction is recorded and reviewed later, time delays may still beminimized. In addition, near instantaneous feedback may be given to anagent to attempt to minimize problems with script compliance.

A still further advantage of the described systems and methods is theprovision of panel-level playback and review of a voice interaction inthe quality assurance process. This provides more effective andefficient methods of quality assurance in, for example, a call centeroperation.

Other and further advantages are described below and still others willbe apparent from a review of the descriptions contained herein.

The communications systems and script compliance methods may optionallyinclude additional, or fewer, features and functionality than thosedescribed herein for the preferred embodiments while still obtaining thebenefits described. The inventions described herein are not limited tothe specific embodiments described, or to the specific equipment,features, or functionality described for the apparatus and methods ofthe examples contained herein. These examples are provided toillustrate, but not to limit the inventions described.

The preferred embodiments include several aspects generally directed tovoice communications apparatus and methods, several of which aredescribed below. The primary preferred embodiment is a script complianceapparatus and method particularly adapted for use in a call center, andmost particularly in a telemarketing application. While this embodimentis described in detail herein, it will be understood by those skilled inthe art that other and further aspects and applications are possible.For example, the systems and methods may be adapted for use in callcenters for applications other than telemarketing, or for voiceinteractions not associated with call centers or telemarketingoperations. The following description is not intended to limit the scopeof the described inventions, which are instead set forth in the appendedclaims.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a block diagram of one implementation of the apparatus andmethods of these inventions. The diagram in FIG. 1 reflects aspects of acall center implementation, though it will be understood that thevarious structures and functionalities may be extended to otherimplementations, including face-to-face voice interactions, electroniccommerce, telephone, web, or wireless-based based information services,and the like. The communications system shown in FIG. 1 includes a userinterface 10, a communications network 12, and a call center 14, eachdescribed in further detail below.

The user interface 10 provides the function of allowing a system user,such as a telemarketing customer, to conduct a voice communication witha telemarketing services provider. The user interface 10 may be astandard function telephone, a video telephone, a wireless communicationdevice, an internet-based communication device, or other instrumentadapted to support voice communication. In the preferred embodiment, theuser interface is a standard telephone.

The communications network 12 provides the function of transmitting avoice signal between the user interface and the call center.Accordingly, the communications network 12 may include an analog ordigital telephone network, an internet-based network, a wirelessnetwork, or any voice communications supporting network. Thecommunications network 12 supports voice communications between a systemuser using the user interface communication device and, in the preferredembodiment, the call center 14. In the preferred embodiment, thecommunications network is a standard telephone service network providedby a long distance and/or local service carrier such as AT&T, Sprint,MCI, or others.

The call center 14 serves as a call termination and servicing point, andmay be provided having any number of features, functions, andstructures. In the typical call center, a call control component isprovided to automatically receive and route calls to one or moretelemarketing agents working at agent workstations within the callcenter. An agent workstation may include only a telephone, but it istypically provided with a networked computer and terminal used tosupport the agent functions. For example, a central database containingcustomer information and information relating to goods, services, orother offerings being provided by the telemarketer is typically providedand is accessible by the computers and terminals located at the agentworkstations. When a telemarketing call is being processed, informationrelating to that call (e.g., customer identification information,product offerings information, credit card information, etc.) areautomatically sent by the central database to the agent terminal in a“screen pop.” The agent then reads information from the computerterminal as the call is processed, and enters new information as it isobtained during the call.

FIG. 2 shows additional details of the call center 14 and, inparticular, an embodiment representing an inbound call center. The callcenter 14 includes a programmable switch 16 that operates to receiveincoming calls and to provide an interface for access to calls, calldata, and other call center operations. The call center also preferablycontains an automatic call distributor (ACD) 18 for routing calls toagents according to pre-determined criteria. While these primaryfunctions of the switch and ACD are described, other details andfunctions of these devices are generally known in the art, and will notbe discussed here.

Three agent workstations 20 a-c are shown in the call center in FIG. 2.It is possible to have any number of agent workstations at the callcenter or, alternatively, to provide off-site agents that are able toaccess the call center remotely by another voice communications networknot shown. In the case of an inbound telemarketing campaign usingmultiple agents, the switch and ACD cooperate to route calls to theappropriate location where an agent is able to process the calls. Theagent workstation also includes a computer terminal at which data may beaccessed by the agent. Typical call centers utilize computer-telephoneintegration (CTI) in which telephone number information (automaticnumber identification (ANI) or dialed number information service (DNIS))is associated with other customer information stored on a database thatis then accessed in real-time during a telemarketing call and a “screenpop” containing this information occurs at the agent workstationterminal. Additional information concerning the goods, services, orother offerings is also provided to the agent workstation terminal. Acentral computer 22 is shown in FIG. 2 having a network connection toeach of the agent workstations, and a connection to the switch to obtaincaller information from the incoming call. The details of the centralcomputer and network are beyond the scope of the present inventions, andare therefore not discussed further here. Moreover, it is typical toprovide a call center with other features and functions desired for agiven call center application. Although these additional features andfunctions are not explicitly described herein, those skilled in the artwill recognize that they may be added to the described system consistentwith the needs of the given application.

In a particular preferred form, data is provided to the agentworkstations during calls in a series of “panels”, with each panel beingassociated with a particular script or portion of a script. The scriptsare prepared as a part of a telemarketing campaign, and include theinformation needed to be given to the customer in a form intended to beeffective and efficient to achieve its purpose. In particular, in atypical campaign, a telemarketer strives to obtain the most efficientresult in the shortest transaction time in order to decrease on-linecosts. The scripts are, therefore, typically highly-developed and testedto determine their effectiveness. A telemarketing campaign can besignificantly undermined by an agent's failure to closely follow ascript.

In addition, by presenting script information in panel form, a qualityassurance process may preferably be coordinated with the scriptingprocess to provide panel-level playback. This panel-level playback, asopposed to the need to play back and/or navigate through an entiretelemarketing voice interaction to review a certain portion of it, is asignificant advantage provided by the described system.

Accordingly, a script compliance module 24 is included in the callcenter. The script compliance module 24 is a software package that isshown in FIG. 2 as having an interface with the central computer, butits location within the call center is optional, as long as access isavailable to the digitized voice interaction. The script compliancemodule 24 performs several functions within the call center, as setforth in more detail below. The script compliance module includes anadvanced speech recognition (ASR) component whereby a voice interactionbetween a customer and an agent may be analyzed and evaluated forcompliance with an expected standard. As discussed below, the scriptcompliance module may be constructed to operate in real-time, i.e., asthe voice interaction takes place, or, preferably, it may include arecording capability such that voice interactions are reviewed andevaluated at a later time.

The ASR component of the script compliance module is supported byproviding an appropriate ASR software package. These ASR softwarepackages are commercially available, and examples include thoseavailable from Nuance Communications (Menlo Park, Calif.) andSpeechworks International, Inc. (Boston, Mass.). A detailed descriptionof speech recognition technology is not necessary to understand thesystems and methods described herein. Briefly, however, the ASRcomponent is adapted to capture a voice signal and convert it to digitalform (if not presented to the ASR component in digital form already).The digital signal is then converted to a spectral representation thatundergoes an analysis to match the spectral representation to a writtenvocabulary, and converts the voice signal to written text. Currentlyavailable systems are able to analyze continuous, multi-lingual,multi-dialect speech from in a speaker-independent manner and convert itto its corresponding text form.

As noted, the script compliance module 24 may be adapted to operate inreal-time by including a component for converting the voice interactionto digital form for direct analysis by the ASR software package. In thatcase, the voice interactions are preferably captured live and feddirectly to the digital converter and the ASR software package foranalysis. Optionally, the script compliance module 24 may be adapted toanalyze recorded voice interactions. In particular, and preferably, thescript compliance module 24 or other system component may include one ofthe commercially available audio recording and monitoring systems suchas those available from NICE Systems Ltd. or Witness Systems, Inc. Insuch a case, the voice interaction recorded by the audio recording andmonitoring system may supply audio files to the ASR software package foranalysis. Because recordings of the voice interactions may be useful toa call center administrator for other purposes, related or not to scriptcompliance, the preferred embodiment includes a voice interactionrecording component such as those described above.

The script compliance module 24 preferably includes a scripting package26, discussed in more detail below. The scripting package 26 is depictedgraphically in FIG. 3, and includes the following components:

First, one or more call scripts 28 are provided. The call scripts 28 maybe maintained in the script compliance module, or, preferably, they maybe maintained on the central computer and accessible by the scriptcompliance module. The call scripts 28 are accessed during the voiceinteraction and contain the information to be read by the agent to thecustomer during the voice interaction. As noted above, the call scripts28 are preferably presented in separate panels containing discreteportions of the overall call script. As an agent progresses through acall, the agent moves from a first panel, to a second, to a third, andso on. A single offer of a good or service may be contained on a singlepanel, or on several panels. Alternatively, several offers may bepresented during a single call.

Second, a log record layout module 30 is provided. A log record ispreferably created for each voice interaction taking place at the callcenter. The log record layout includes data fields for all data thatcould be captured during calls, and log records are maintained as partof the ongoing function of the call center. The data fields will, ofcourse, vary based upon the operation of the call center. Typical datafields will include date and time of call, length of call, agentidentity, customer identity, and any transaction data obtained duringthe call. Some data fields may be filled automatically during a call,such as date, time, agent identity, and the like, while others may befilled by the agent during the call.

Third, an ASR text module 32 is provided. The ASR text is a referencetext to be used by the ASR component of the script compliance module,and corresponds to the call scripts described above. As with the callscripts, the ASR text is preferably provided in separate panels.

Fourth, a set of action rules 34 is provided. In the most general sense,the action rules take the output of the ASR component evaluation of thevoice interaction and, based thereon, direct an action to be taken byanother component of the script compliance module. The output of the ASRcomponent evaluation may comprise, for example, a numerical scoreindicating the degree to which the voice interaction complied with theASR text. The actions directed by the set of action rules may comprise,for example, a quality assurance (QA) action to be taken based upon thenumerical score. For example, scores less than 60 may be sent to a QAauthority for review, scores between 60 and 80 may have random callsselected for review by a QA authority, and scores over 80 may be used todrive a QA incentive program. These are examples only. The determinationof specific standards and actions will depend, of course, on the type ofapplication.

Fifth, a panel timestamp logging feature 36 is provided. The paneltimestamp logging feature assigns a time displacement timestamp to eachpanel as it is presented and viewed by an agent during a voiceinteraction with a customer. For example, in a voice interaction inwhich a first panel is processed in 15 seconds and a second panel isprocessed in 12 seconds, the first panel will log from 0:00:00 to0:00:15 (i.e., the duration of the voice interaction relating to thefirst panel) and the next panel will log from 0:00:16 to 0:00:27. Thisprogression continues for each panel used during the voice interaction.A log of the timestamps is maintained for each voice interaction. Thetimestamps are then preferably used in the quality assurance process tofacilitate panel-level playback of the voice interaction.

The communications system operation will now be described in referenceto FIG. 4, and in the context of a telemarketing call. A telemarketingagent and a customer engage in a voice interaction during which theagent processes the call 40, i.e., the agent reads from scriptspresented on the workstation terminal and enters information in thefields provided according to responses obtained from the customer. Asnoted above, the scripts are preferably presented to the agent inpanels, with each panel corresponding to a portion of the overallscript, or to a separate script. The time displacement per panel islogged 42 as a portion of the log record. Once the call is completed 44,all data obtained during the call is logged according to the log recordlayout. If a voice recording or video recording are made, they too arelogged and stored for later use in the QA process.

The QA process 46 is next begun by retrieving the voice interactionrecord. The log record is also retrieved and reviewed to determine whichscripts were to have been recited by the agent, and the correspondingASR texts are retrieved for the ASR analysis. The voice and/or videorecording is preferably divided into panel-level segments 48 for reviewand evaluation, and the log record is evaluated 50 to determine theexpected ASR text by panel. A comparison of the voice interaction withthe ASR text is then performed by the ASR component in order todetermine the degree of compliance of the voice interaction with the ASRtext. In the preferred embodiment, the ASR component assigns scores 52based upon the level of accuracy of the comparison. Confidence-levelthresholds are used in evaluating the match accuracy. After each panelis evaluated and scored, an overall score may be determined. Thepanel-level scores and overall scores are next used to determine anyaction 54 to be taken as provided in the pre-determined set of actionrules. Examples of such actions include sending an e-mail containing thefile for review, providing a feedback message to the agent, or otheractions tailored to the particular application.

As an extension of the QA process, the stored voice interaction and logrecords may be retrieved from the system by a QA authority at a latertime for additional analysis. The records may be used to review theassigned panel-level and/or overall compliance scores. In addition, allor a portion of the voice and/or video recording may be played back foranalysis. The logging process included in the scripting package allowspanel-level playback of the voice interaction either in conjunctionwith, or independent from the ASR analyzing function of the system.

A block diagram providing an additional representation of the callcenter actions is shown in FIG. 5. The ASR Interface 56 is used to setthe initial conditions of the ASR component of the script compliancemodule. The initial conditions of the ASR component include thedefinitions of the ASR texts 58, the definitions of the evaluationconditions 60—i.e., the point in time during a voice interaction a givenASR text is expected to be read—and the action rules 62, discussedabove. Any changes or modifications to the initial conditions are madeby accessing these features via the ASR Interface 56 and making thedesired changes.

When a call is processed 64, a voice recording is made 66 and,optionally, a video recording 68 is made. Each of these recordings maybe separately logged and stored for later retrieval as needed. A logrecord 70 is created of the voice interaction during the call and isused, along with the ASR initial conditions, to build an expected speechlist 72 to which the voice recording will be compared. For example, as acall is processed, the agent will view, read from, and enter informationinto several panels according to the nature and flow of the call. Theinteractive logic concerning all branching of the scripts and panelsprovided to the agent during the call is maintained on the centralcomputer or, alternatively, in the script compliance module, anddictates which call scripts are presented to the agent at each step ofthe call. The evaluation conditions contain the information coordinatingthe voice interaction, scripts, panels, and ASR texts. These are used tobuild the expected speech list.

The actual voice recording is then compared 74 to the ASR text todetermine compliance. A score is generated 76 indicating the measuredcompliance, taking into account the confidence-level thresholds of theASR component, and the score is evaluated 78 against pre-determinedstandards. The pre-determined standards may be static or may vary, andmay be included in the ASR evaluation conditions. For example, an 80%accuracy score may be sufficient for one script or script portion, but a90% accuracy score may be required for another script or portion. Thescore and evaluation may be added to a report 80 of the call for laterretrieval. An action 82 is next taken based upon the score according tothe pre-determined set of action rules. Examples of these actionsinclude e-mailing a report (which may optionally include a copy of thedigital recording of the voice interaction) to a QA authority 84,providing a feedback message directly to the agent 86, or any other 88action appropriate for the given application.

FIG. 6 is a data flow diagram illustrating processing and componentsrelated to providing feedback to agents on particular aspects of theirhandling of given interactions. These aspects provide methods, systems,and computer-readable media for improving agent performance, with themethod including at least identifying one or more interactions 602 thatare or were handled by one or more given agents 620, with theseinteractions being deficient in some aspect. A voice record 606 of atleast a portion of a deficient interaction is obtained, along with afurther voice record 614 of at least a portion of another interaction inwhich the at least one aspect is not deficient. Data 622 representing atleast the portions of the voice record and the further voice record arethen transmitted as feedback to the agent 620 conducing the interaction.

Typically, but not necessarily exclusively, the deficiency referencedabove involves at least one metric related to quality assurance (QA),and identifying the deficiency may include identifying a QA-relatedmetric that is applicable to an interaction. Thus, identifying a“deficient” interaction can include analyzing given interactions againstone or more QA-related parameters or metrics, and determining that theagent 620 failed to meet these parameters or metrics during one or moreinteractions. These metrics can deal with script compliance issues, asdiscussed above, wherein one or more scripts govern the agent's conductof given interactions with third parties. Other illustrative butnon-limiting examples of such metrics can involve general capture andentry of data provided by these third parties (addresses, credit cardnumbers, etc.) into computer-based systems, responding correctly toquestions posed by these third parties, correct pronunciation of productnames, or the like. These metrics can also be somewhat subjective innature, focusing in matter such as pace of the interactions, tone andmanner of the agent's voice, and the like.

Voice records 602 for interactions that are processed according to theteaching herein can include at least a portion of one or moreinteractions processed by an agent physically located at a call center,which can be either an in-house call center run by a given company orfirm, or a third-party call center to which such companies or firmsmight outsource call-handling functions. Conversely, the voice recordscan be created to store data resulting from or relating to interactionshandled by an agent physically located in a location remote from a callcenter. Such agents are known as remote agents, or if the agent isworking from his or her residence, as a “home agent” or “home-basedagent”. In the context of home- or remotely-based agents, such agentsare not subject to immediate, in-person supervision, so the need toproactively detect and investigate script compliance or QA issues of thetype discussed herein can be particularly acute with these agents,perhaps even more so than with call center-based agents who aresupervised in-person. Finally, the invention as described herein can bedeployed at a call center that either receives incoming or inbound callsor that generates or originates outgoing or outbound calls. In anyevent, a data store 604 can store or archive these voice records 602 foranalysis.

The second or further voice record 614 that is provided as at least apart of the feedback to the agent 620 can be obtained from at least aportion of a pre-recorded interaction that is stored in a library ordata store 618 containing one or more exemplary voice records madeavailable for future reference. This data store 618 can be adapted tocorrelate respective portions of a pre-defined script governing at leastpart of various types of interactions to respective fields in the datastore 618 that store respective suggested voice records 616corresponding to those portions of the script. However, if apre-existing voice record 616 suitable for feedback to the agent 620 isnot available in the data store or library 618, at least a portion of asuitable voice record 610 for another interaction that occurscontemporaneously with or subsequently to the interaction at issue canbe recorded using known recording apparatus 612 and provided to theagent 620.

In any event, the second or further voice record 614 is provided to theagent 620 as an exemplar, guideline, example, constructive criticism, orsuggestion for improving the performance of the agent 620. This audio orvocal feedback 622 can be valuable in instances where merely providing atextual representation of the second or further voice record 614 (suchas the output of a speech recognition engine) would not be as helpful,for example, when the aspect of the agent's performance needingimprovement centers on tone-of-voice or other similar parameters. Also,more than one further voice records 614 can be provided as exemplars, asthe case may be.

Once the deficient aspect of the given interaction is identified and thesecond or more voice records 614 are obtained as exemplars, thedeficient voice record 606 and the exemplar voice record 614 can betransmitted as feedback 622 to the agent 620, for example by emailingdata representing the voice record 606 and the further voice record 614to the agent 620. Various known transmission methods may be chosen torealize this function by those skilled in the art, given the teachingherein and the requirements of a given application.

Further aspects of the invention can include transmitting to the agent620 one or more representative screen shots of a computer screen thatare related to whatever aspect of the agent's performance needsimprovement. As a non-limiting example, if an agent 620 has persistenttrouble with accurate data entry, the screen shot might depict acomputer screen with particular areas highlighted where the agent 620made mistakes in such data entry. In general, the screen shots may helpfurther to reinforce the feedback 622 to the agent 620 when the screenshots provided in connection with the voice records 606 and 614. Also,where script compliance issues arise, a portion of the script with whichthe agent 620 was non-complaint may be transmitted to the agent 620 toenable the agent 620 to focus on that portion when handling futuresimilar interactions. In other cases, the feedback 622 transmitted tothe agent 620 could include pointers or other links directing the agent620 to remedial or training materials that address whatever aspect ofthe agent's performance needs attention. These remedial or trainingmaterials can include either hard copies of training manuals ordocuments, software-based instruction materials, or portions of both.

For agents 620 physically located in call centers, it may be necessaryto convert the voice records into a format suitable for transmission tothe agent 620, for example, between a format suitable for storage orarchival in a central data store into a format suitable for e-mail orother transmission. This conversion can also include employingcompression algorithms or the like as may be necessitated by bandwidthlimitations or constraints applicable to data transmissions within thecall center enterprise. Similar considerations may hold with home-basedor remote agents 620 physically located remotely from the call center,given limitations or constraints applicable to data transmissionsoutside the call center enterprise to such agents 620.
